UBA2016A/15/15A:600 V fluorescent lamp driver with PFC, linear dimming and boost function
The UBA2016A/15/15A are high voltage Integrated Circuits (IC) intended to drive fluorescent lamps with filaments such as Tube Lamps (TL) and Compact Fluorescent Lamps (CFL) in general lighting applications. The IC comprises a fluorescent lamp control module, half-bridge driver, built-in critical conduction mode Power Factor Correction(PFC) controller/driver and several protection mechanisms. The IC drives fluorescent lamp(s) using a half-bridge circuit made of two MOSFETs with a supply voltage of up to 600 V.
The UBA2016A/15/15A are designed to be supplied by a start-up bleeder resistor and a dV/dt supply from the half-bridge circuit, or any other auxiliary supply derived from the half-bridge or the PFC. The supply current of the IC is low. An internal clamp limits the supply voltage.

UBA2015AP 120 V (AC) 評(píng)估板
This evaluation board is intended to build applications with the UBA2016A, UBA2015A and UBA2015 ballast controller family. This document describes the specification and use of the board. Default, this ballast design is intended to drive one TL5HE35W lamp with the UBA2015AP. However, several options are provided on the board to use it with the UBA2016AP and UBA2015P.
